BOLTING-REEL ATTACHMENT.

SPECIFICATION forming part 0! Letters Patent No. 313,988, dated March17, 1885 Application filed June 21, 1884. (X0 model.)

To all whom it may concern.-

Be it known that I, FREDRIoII BURCK- HARDT, of St. GharlesJin the countyof St. Charles and State of Missouri, have invented a certain new anduseful Improvement in Bolting-Reel Attachments, of which the followingis a full, clear, and exact description, referencebeinghadtotheaccompanying drawings, forming part of this specification, and

in which Figure 1 is a vertical transverse section of a flour-bolthaving my improvement, taken on line 1 1, Fig. 2; and Fig. 2 is a sideelevation with .part of the casing or housingremoved.

My invention relates to an attachment for cleaning the cloth of the reelautomatically; and my invention consists in features of noveltyhereinafter fully described, and pointed out in the claims.

Referring to the drawings, A represents a bolting-reel of ordinaryconstruction inclosed within a common casing or housing, B. Secured tothe heads A of the reel are pins or projections 0, preferably one(oneach disk) at each corner of the reel, as shown in Fig. 2.

D represents a knocker consisting, preferably, of a brush, supported onthe free ends of arms I, hinged to the housing, as shown at I, one ateach end of the reel. These arms are held against the pins 0 as the reelrevolves by springs J; but the pins hold the arms far enough back forthe knocker not to come in contact with the reel, except when the pinscome opposite depressions or notches L in the arms, and then the springsforce the arms inward, causing the knocker to strike the cloth of thereel to clean it. The depressions or notches are quite short, so that assoon as the knocker strikes the reel it is forced outward or back again,so as not ,to rub on the reel.

My improved knocker will thus keep the FREDRIOH BURcKHan-Dr.
